Subject: [ cf-dev ] MX "Locking Up" + other issues


Right...

We seem to be having issues (in fact, three issues which may be related)
with a couple of our MX boxes (both running on RedHat7.2).

1.
For no _apparent_ reason, the cfserver locks up.  By lock up, what seems
to be happening is a request starts running and for some reason just
hangs and doesn't time out.  Over time another and another do the same
until all available connections are used up - after that the queued
requests just build up and up and we have to restart CF.

E.g. from cfstat (taken every 30 seconds, request timeout is also set to
30 seconds):

    Reqs  Reqs  Reqs 
    Q'ed  Run'g TO'ed
    0     2     0
    0     9     0
    7     10    0

Neither of the servers is under any (excessive) load.  I have been able
to recreate the problem on one particular page on one of the servers --
it is a page that contains a <cffile> upload tag to allow the user to
(duh) upload a file to the server.  I haven't worked out where the issue
is occuring 

The problem only seems to have occurred since I installed updater 3, and
it doesn't happen for _every_ file upload page (i.e. there are other
templates that use <cffile action="upload"> running on the same box
without a problem.

Is there any way to check exactly _which_ templates are "stalling"?  The
web server logs don't show anything because they only write once the
page has been delivered (which never happens...).  Nothing appears in
either the application or exception logs.

2.
Something (somewhere) seems to be using up a hell-of-a-lot of memory.
Running a top command shows the cfusion process using up appx. 200Mb,
but the total memory usage is well over 800Mb.  There is nothing running
on these boxes except CF and apache..

3.
Both boxes give errors on a restart of CF.  A cut down version (getting
rid of all the stack trace) of the output is below.  Both servers have
exactly the same errors, but again do not give the error every time.

Any pointers in the right direction for any of the issues would be
great!

Cheers,

Tim.
